[Mr. Wyndham]

If you have a movie playing while your driving, and a cop catches you...they can definitely pull you over.

So besides being probably a little bit illegal, I'd say find out how the computer senses the parking brake is engaged (a wire, a switch, electric connection, etc.) , and then trick it into believing the brake is on all the time...
I'm not sure how yours works exactly, so this is the best advise I can give. Hope I could help
